Subway tiles in the kitchen are a design classic that will stand the test of time. No surprise, given that their classic brick-like shape allows them to blend seamlessly into traditional, modern, industrial, and even country decor. Oh, and it doesn't hurt that they're also affordable! But if you're interested in turning the luxe factor up a notch — and you can swing it — white marble subway tiles are just as timeless.
